Explain the 2 different answers you can get when solving an equation and the variable is eliminated.

Answers

Answer 1

When you're solving an equation, there are three possibilities.  Two of which are chosen if your statement is true or not.

If you're able to get x alone, there is one solution.  However, If all of the variables are eliminated and you're left with a false statement, that will be no solution. Example: 1=5? False.

If all of the variables are eliminated and you're left with a true statement, that solution is all real numbers. Example: 5=5? True.

↑ the second equation is y smaller than or equal to but i wont let me type that so :) PLZ help! ty!!♡

Answers

Start by graphing each line.

• Because the first inequality is smaller than, it will have a dotted (- - -) line.

• Because the second inequality is smaller than or equal to, it will have a solid line (---).

Then, plug in points to see where your shading will go. If the statement is true (x = x), you will shade that area along the line.

[tex]y < 3x + 2[/tex]

[tex](0) < 3(0) + 2[/tex]

[tex]0 < 2[/tex]

0 is less than 2.

Do the same step for the other equation. Your solution to the problem is any point that lies between the shading from both inequalities (where the blue and red meet).

Answers

Answer:

C

Step-by-step explanation:

So we have the following sequence:

-7, -3, 1, 5...

As given, the (direct) formula for any arithmetic sequence is:

[tex]a_n=a_1+d(n-1)[/tex]

Where aₙ is the value of the nth term, a₁ is the value of the first term, and d is the common difference.

From the sequence, we can see that the initial/first term is -7. Thus, a₁ is -7.

And we can see that each subsequent number if 4 greater than the previous one. Thus, the common difference is +4.

Therefore, plugging these into our equation, we have:

[tex]a_n=-7+4(n-1)[/tex]

The answer is C.

Tickets to a school dance are sold for $10 each. The student council spent a total of $400 on set-up costs for the dance. The school's profit (p
), in dollars, from the dance depends on the number of tickets sold (1).
Which function describes the relationship between p and 1?

Answers

Answer:

P(t) = 10t - 400

Step-by-step explanation:

Selling price of each ticket = $10

Cost of setting up the dance= $400

Profit = Revenue - cost

Revenue = price × quantity

Revenue that will maximize profit = 10t

where t= quantity of tickets that maximises profits

Cost = $400

Profit(t) = Revenue - cost

P(t)= 10t - 400

We want to find the equation that represents the school's profit. We will get:

P(x) = $10*x - $400

We know that the tickets to the school dance are sold for $10 each, then the revenue, if they sell x tickets, is just:

r(x) = $10*x

And we know that they spent a total of $400.

Remember that profit is defined as the difference between revenue and costs, so the profit equation is just:

P(x) = $10*x - $400

Write an equation of the line below.
(0,-2) (8,-4)

Answers

Answer:

[tex]y = - \frac{1}{4} x - 2[/tex]

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

First of all to find the equation of the line we must first find the slope.

The slope of the line using points

(0,-2) (8,-4) is

[tex]m = \frac{ - 4 + 2}{8 - 0} = - \frac{2}{8} = - \frac{1}{4} [/tex]

Now using one of the points and the slope we can find the equation of the line.

Equation of the line using point (0 , - 2) and slope - 1/4 is

[tex]y + 2 = - \frac{1}{4} (x - 0) \\ y + 2 = - \frac{1}{4} x[/tex]

We have the final answer as

[tex]y = - \frac{1}{4} x - 2[/tex]

The average annual tuition for four-year private colleges increased by 5.9 percent from last year. The average cost last year was $31,250. What is the average cost this year?

Answers

Answer:

The average cost this year = $33,093.75

Step-by-step explanation:

The computation of the average cost this year is shown below:

Given that

The average cost for the last year = $31,250

Increased percentage = 5.9%

Based on the above information, the average cost this year is

= The average cost for the last year × (1 + Increased percentage)

= $31,250 × (1 + 0.059)

= $31,250 × 1.059

= $33,093.75

Leonardo ate a 3/5 of cheeseburger and an entire salad for dinner. The salad contained 70 calories and the entire meal contained 1650 calories. Which equation can determine the value, c, the number of calories in the cheeseburger?

Answers

Answer:

3/5 c + 70 = 1650.

Step-by-step explanation:

If c is the number of calories in the cheeseburger, we can see that the entire number of calories for the meal is 3/5 c + 70 = 1650.

If we want to isolate c, we can subtract both sides by 70.

3/5 c = 1580

Answer:

C = [5(1650 - 70)]/3

Step-by-step explanation:

We write the equation: 1650 = 70 + 3C/5

Subtract 70 from both sides: 1650 - 70 = 3C/5

Multiply 5 on both sides: 5(1650 - 70) = 3C

Divide 3 on both sides : C = [5(1650 - 70)]/3

A Question of EthicsStare Decisis. On July 5, 1884, Dudley, Stephens, and Brooks"all able-bodied English seamen"and a teenage English boy were cast adrift in a lifeboat following a storm at sea. They had no water with them in the boat, and all they had for sustenance were two one-pound tins of turnips. On July 24, Dudley proposed that one of the four in the lifeboat be sacrificed to save the others. Stephens agreed with Dudley, but Brooks refused to consentand the boy was never asked for his opinion. On July 25, Dudley killed the boy, and the three men then fed on the boys body and blood.
